本文主要探讨大安市盐碱地小井种稻的水稻公顷产量 6000 公斤以上的丰产栽培技术。主要措施为:浅翻(耙);增施有机肥、客土(砂)压碱;洗盐排碱;提高水温促早熟;氮、磷、钾及锌肥配合,分期适量施肥;及时防病虫草害等综合措施。明确在盐碱、井灌冷水条件下,单位面积穗数和粒数是限制当地水稻产量的主导因素。提出以 m~2穗数在 500～650,每穗平均粒数 70—80,结实率 80％以上,千粒重23克以上的穗粒兼顾途径取得丰产的结构设计。
This article mainly discusses the high-yield cultivation techniques of producing more than 6,000 kg of rice per hectare in saline soil of Da’an City. The main measures are as follows: shallow turning (rake); organic fertilizer added, soil (sand) caustic soda; salt washing alkali; water temperature to promote early maturity; nitrogen, phosphorus, potassium and zinc fertilizer, staged amount of fertilization; Cordyceps harm and other comprehensive measures. Clear salt and alkali, well irrigation cold water conditions, the number of spikes and grain per unit area is the main factor limiting the yield of local rice. It is proposed that the structure design with high yield should be made by taking the spikelets with m ~ 2 spike number from 500 to 650, the average grain number from 70-80 per panicle, the seed setting rate above 80%, and the grain weight over 23 g.
